Tapes and Adhesives Archives

Many industrial manufacturing environments require workers to wear protective gloves, including during electronics and medical device production and assembly. Latex gloves not only protect workers from harmful chemicals but also protect products from worker contact and contamination during manufacturing Read more

Save a few steps--and some money--with the Pace 925 SMT Rework System

You may or may not have heard about Metcal’s new soldering station, the CV-5200. The evolutionary tool removes much of the reliance on visual inspection of hand-soldered joints and adds a second, more technology-driven method for validating a successful Read more

The ubiquitous threaded fastener. It’s arguably the most important detachable hardware ever. You rely upon multiple fasteners frequently, if not daily, to hold together your most critical parts. So, making sure you prevent threaded fastener failure is paramount to the success of your business.

Fasteners fail for two reasons: tension relaxation and self-loosening. Tension relaxation is caused by temperature changes, which make your bolts and substrate materials expand and contract. Self-loosening, caused by the lateral sliding between fastener contact surfaces, continues to be a problem even with mechanical locking methods.

Chemical threadlocking adhesives, however, are inexpensive and permanently prevent fastener failure. Loctite® threadlockers come in four grades for a broad array of applications and are color-coded for easy identification: red, blue, green and purple.

Red is the highest strength. It is so powerful it requires heat to be disassembled. The blue threadlocker is medium strength and can be removed with hand tools. It is available as a liquid and a semisolid. Loctite also makes the QuickTape®249™ Threadlocker, which is the only one of its kind in the world. The green threadlocker is recommended for locking preassembled fasteners such as electrical connectors and set screws. Green is categorized medium-to-high strength for wicking and is also available in liquid form. You can remove it with heat or hand tools. Loctite’s purple threadlocker is ideally suited for low-strength metals such as aluminum and brass.

Regardless of your application, chemical threadlocking adhesives for metal-to-metal applications cure to a hard thermoset plastic for the cure of a lifetime.

Rain and wind. Extreme heat, moisture and more—LEDs need to work properly regardless of the elements. While adhesives have been perceived as slow and expensive assembly methods, the correct LED adhesive for harsh environments not only expedites the manufacturing process but also perfects it.

Adhesives perform well on glass, metal, ceramic and most plastic substrates. They provide excellent chemical and solvent resistance, serve as insulators and can be used in high-speed production environments. And, when it comes to LED assembly, these benefits are critical. In some cases, choosing the right adhesive for the job at hand also means cost-effective production that would have been impossible with mechanical fasteners.

For every type of LED package, from circuit board mounting to completed luminaires, adhesives and sealants play an important role, including long-term protection from vibration and shock. If you’re operating in an extreme environment, explore modern LED adhesives and sealants, like those from Henkel Loctite®, that perform over a long range of temperatures and provide excellent chemical, humidity and UV resistance.

With the latest major addition to the All-Spec Loctite® line, we are excited for our clients to try out the Bond-A-Matic adhesive dispensing system, which has a pressure range of 0 to 15 psi, ideal for low-viscosity adhesives under 3,000 cPs. Here are three essential benefits of this system:

#1 Precision = Efficiency and Lower Cost of Ownership

With this model, Loctite focused on a system that dispensed adhesive in the most efficient manner possible. With the adjustable pressure regulator, users have increased control of the amount of solution dispensed, significantly reducing waste.

#2 Adaptable

The Bond-A-Matic has a diverse dispenser that is compatible with a variety of bottles and squeeze tube sizes, including:

250-ml bottles

One-pound bottles

One-liter bottles

Two-kilogram bottles

200-gram squeeze tubes

#3 All-Inclusive Kit

Rather than nickel-and-diming its customers, Loctite took the best route possible and offers everything you need to get your adhesive dispensing started in one, complete order. The Bond-A-Matic comes with the following accessories:

Reservoir with ¼” tank fitting

Vari-Drop applicator

Teflon-lined black feedline (¼” outer diameter; 7” long)

Two spring strain reliefs

Anti-bubbler tip and sleeve

Needle assortment kit

Tube of silicone grease
